Specification of Letters Patent. 7 Patented Oct, 30, 191 '7.

Application filed January 5, 1912. Serial No. 669,528.

To all whom it may concern:

Be it known that I, ALEXANDER E. BLooK, a citizen of the United States, and a resident of St. Louis, Missouri, have invented certain new and useful Improvements in Machines for Creasing and Stretching Shoes, of which the following is a specification.

My invention relates to improvements in machines for processing shoes, and has for its object to provide a mechanism specially adapted to the application of stretching tools to shoes, more particularly to the soles of shoes; while it is incidentally adapted to or the stretching of any part of the shoe, the apparatus also being provided with means for holding the stretching tools in contact with the shoe, under pressure,'and being provided with means for applying moisture to the work during the operation of stretching or creasing.

In the drawings Figure 1 is a side elevation of the machine embodying my invention.

Fig. 2 is a vertical. view in mid-section of the female stretching member used in connection therewith.

Fig. 3 is a similar View of one form of the male stretching member, in which moisture is applied by means of a sheet of fabric secured about a pin by means of a ring.

Fig. 4: is a similar view of a male member in which a moisture pad is held in a pocketin the upper face of a pin.

As shown in the drawings, I employ a table 7 supported by legs 8, beneath which is the treadle-lever 9 provided with the treadle 10 and counterbalance l1, and mount ed on the hinge 12. The lever-arm 13 is connected to one of the legs 8 by the hinge 14, and is connected to the treadle-lever 9 by the link 15; while at its free end it is connected to the vertical bar 16 by the pin 17. The bar 16 is provided with arack 18 which is adapted to engage with the ratchet 19 on the ratchet-arm 20. The ratchet-arm 20 is L-shaped, its lower arm being provided with the counter-balance 21, and it is pivotally mounted upon the table 7 by means of the pin 22. The overhanging arm 23 is mounted upon the table 7 and is journaled to receive the plunger 24:, which in turn has slidable connection with the lever 25 by means of the pin 26 and slot 27. The lever 25 is secured to the rod 16 by the pin 28 Gopies of this patent may be obtained for five cents each, by addressing the 18; and in this condition and to the arm 23 by the pin 29. The plunger 24 is provided at its lower end with the tool-holder 30, directly beneath which is the upper end 31 of the tool-holding arm 32 which is mounted upon the table 7 It will be observed that the mechanism thus far described is capable of forcing the tool carried by the tool-holder 30 down wardly to contact with the work held by the tool in the tool-holding arm 32, and that the ratchet 19 will.hold the said tools in contact with the work, the machine being used in this manner whenever it is desired to keep the tools in continuous contact with the work. Whenever it is desired to use the machine for the purpose of administering blows to the work, by the reciprocatory movement of the plunger 24, the ratchet-arm 20 will be thrown backward so that the ratchet 19 will not engage with the ratchet the machine may be used. for calking or like purposes.

For the purpose of stretching, the toolholder 30 is provided with a female stretching member33, the tool-holder 30 being provided with set screw 34 to secure the tool in place; and the tool-holding arm 32 will be provided with a male stretching member 35, provided with a moisture pad 36. In the form shown in Fig. 3, a strip of fabric 37 is employed, of a material capable of holding moisture, and secured in place by a ring 38; while in'the form shown in Fig. 4 the male member 35 is provided with a cavity 39 adapted to receive and hold the moisture pad 36.

Having thus described my invention, what I claim as new and desire to have secured to me by the grant of Letters Patent, is

In a machine for creasing and stretching shoes, the combination of a frame; a female stretching member movably mounted in said frame; a male stretching member fixedly mounted in said frame and provided on its working face with a recess; and a'moist-ure pad mounted in said recess.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.

ALEXANDER E. BLOCK.
